"The UK DRI at Imperial brings new perspectives to prevent, delay or reverse dementia. We focus on the earliest stages when benefits to those who may be affected will be greatest." Prof Paul Matthews

1. At a glance
People with Alzheimer’s disease (AD) and other types of dementia experience a variety of progressive symptoms – such as memory loss, mental decline and personality changes. So understandably, much of the current research into dementia is focussed on the brain – to explore what leads to the gradual loss of function and death of neurons.
The UK DRI at Imperial brings together researchers from diverse backgrounds with fresh perspectives. They draws on the university’s unique strengths, resources and focus on science, engineering, medicine and business. The team recognises that the challenges of dementia demand new concepts, new approaches and a diverse range of new research tools and directions. Their holistic approach views the ageing brain in the context of the ageing body, not in isolation. Studies from individual cells through to whole systems are creating a new vision of what can go wrong and lead to dementia. Our multidisciplinary approach brings new expertise to focus on the challenges of dementia research. Investigators are addressing the transition from vulnerability to the expression of neurodegenerative pathology by exploring individual variation across populations, influences of the gut on the brain, mutual interactions between neurons and glia (immune cells) and roles for homeostatic mechanisms of sleep in pathological processes.
The centre aims to identify what goes wrong in the brain at the very earliest stages of dementia and to develop innovative treatments that can correct detrimental changes, which could greatly benefit people who are at increased risk of disease but have not yet developed symptoms – preventing or slowing down the onset of disease.

2. Scientific goals
The researchers at this centre view the ageing brain in the context of the ageing body, using approaches that integrate function – from individual cells through to systems and populations. The objectives are translational so that people with dementia and their families realise the benefits from research as rapidly as possible.
The approach starts from the view that most of the major advances in the understanding of dementia have been drawn from the discovery of genetic determinants of susceptibility. However, these contribute only partially to the expression of disease. An additional major component of this is related to the effects of influences arising from - or acting via - the whole body: co-morbid systemic diseases, the environment and lifestyle. The centre is addressing Alzheimer's disease and related dementia as systemic diseases. In an increasingly sub-specialised clinical and research world, this challenges more usual research strategies.
The approach is built around four investigative themes:
- Circadian Neurobiology
- Metabolomics and Microbiome
- Microcircuits and Brain Systems
The team includes complementary expertise that together have a unique potential to address these questions. It has a critical mass of internationally leading investigators in metabolomics, the microbiome and molecular neuroepidemiology. They have developed, or contribute to, large population studies that provide access to the detailed linkage of the genetic and detailed clinical and lifestyle data of people before they develop dementia.
Other investigators have been leaders in fundamental and clinical investigations of multiple sclerosis, arguably the “paradigmatic” neuroinflammatory, neurodegenerative disorder. The expertise in circadian neurobiology promises to discover novel mechanisms by which altered sleep patterns enhance neuronal stress and accelerate neurodegeneration. Outputs from these programmes together can then be focused on how brain microcircuits become dysfunctional in the early disease and how their associated neuronal systems can be therapeutically modulated bioelectronically.
